Position Sensor Circuit
Position Sensor CircuitDESCRIPTION
The position sensor detects movement of the seat and sends pulse signals to the power seat control ECU. The position sensor sends the pulse signals to the ECU in proportion to the amount of seat movement.
The ECU uses the pulse signals to constantly calculate the position relative to the memory position and returns the seat to the memorized position.
If a malfunction occurs in a position sensor and a sensor signal is not input to the ECU even when the motor operates, the ECU prohibits return operation.
